For several decades, air filters were considered a luxury, but that has recently changed into a necessity. Air purifiers are critical in filtering indoor air by removing hazardous airborne particles and biological elements to provide your home with clean air.
If you've decided to purchase a residential air filtration system, here is a simple checklist to help narrow down your options.
The Type of Air Filter
By design, air purifiers are made up of multiple filters that require periodic replacements. During operation, indoor air passes through pre-filters which retain various particles, including dust, pet dander, and pollen. The atmosphere is further cleaned when it passes through other filters before being released. It's recommended to purchase purifiers with easy-to-clean pre-filters to allow for regular use.
Additionally, opt for air filters that have High-Efficiency Particle Air (HEPA) filter. That's because they have high air filtration capabilities when it comes to eliminating micro-particles, including bacteria, pollen, and mold. You will most likely find carbon filters used alongside these filters for maximum filtration of hazardous gases and chemical elements. Steer clear of UV and ion filters since they contribute to ozone production, which is risky to human health.
Size of Your Room or Home
Based on capacity, there are different types of air filters in the market today. Depending on the equipment's fan speed, most manufacturers determine the air filtration unit's power according to space occupied. Furthermore, there are cases where the physical size of the purifier defines its capacity.
If the unit has electrical filters or ionizers, it can disperse negative ions across the room, making it ideal for vast spaces. Furthermore, consider using an air purification system with more prominent coverage for congested areas.
The Noise Rating
Another factor to consider is the noise rating of your air purifier. Since air filtration systems contain fans, they usually emit some noises when in operation. But some air filtration units are louder than others when cleaning your air, and it's imperative to choose wisely. For example, you don't want a relatively noisy air purifier in your bedroom, you can choose one that has a noise rating under 50dB.
Purchase and Maintenance Costs
Finally, the cost of purchasing, servicing, and maintaining your air filtration system is a crucial factor to consider. While some filtration units found on the market can be cheaper, they might have superior performance. That's something that can be affected by various factors, including brands and construction technology. Therefore, base your purchase decision on capacity and performance quality instead of looking at brand popularity.
